Résumé : A method is described for the isolation of starfish oocytes nucleoli in sucrose media. Guanine and 5-adenylic acid were found in the acid-soluble fraction of these PCA extracted nucleoli. The percentage of ARN is only 5% of the dry weight of the nucleolus. Both guanase and adenosine desaminase are absent from the nucleoli but, on the other hand, nucleoside phosphorylase and the enzyme synthesizing cozymase were found to be highly concentrated. © 1984.
